Benchmarking Infrastructure Costs: A Case of Road and Water Basket of Locally-Obtained Commodities (BLOC)

By Centre for Comparative Construction Research (Bond University), The Economist Intelligence Unit (EIU) and AIIB Staff

Although understanding drivers of infrastructure cost is an important part of cost management, data on costs are hard to obtain. Most importantly, cross-country comparisons of infrastructure costs are difficult to collect due to heterogeneity in infrastructure types and differences in country contexts. By standardizing input quantities and qualities of a road and a water infrastructure as well as accounting for currency variations, this paper documents a methodology to create a cross- city measure of infrastructure costs. Based on this benchmarking methodology, the derived cost differentials between pilot cities are attributable to factors other than quality, quantity, and the exchange rate.

Protectionism and Trade in Renewable Energy Infrastructure

By Anne Ong Lopez

International trade in renewable energy infrastructure is essential for countries to meet their development and environmental objectives such as the Sustainable Development Goals. This paper explores the role of protectionism in renewable energy. Using detailed product-level data on imports, tariff and non-tariff measures, it presents evidence that burdensome measures negatively impact trade flows in this infrastructure. Results further suggest that these measures may have heterogenous impact on exporting countries depending on their level of development. This points to the need to lower costs to support renewable energy development.

Deficits and Crowding Out Through Private Loan Spreads

By Jang Ping Thia

Post crisis, bank loan spreads increased and have remained elevated despite central bank actions, low LIBOR rates and observed Treasury yields. Using large syndicated loan dataset, this paper estimates that a one percentage point to GDP increase in government deficits increases spreads by around nine basis points on average. This is consistent with partial crowding out. Weaker country risk ratings, larger loan size also increase spreads. Finally, the paper provides evidence that US deficit spending results in a crowding out of around one-half in loan markets and have some crowding out of loans in other markets.

Impact of Infrastructure Investment on Developed and Developing Economies

By Xuehui Han, Jiaqi Su and Jang Ping Thia

This paper uses two longitudinal datasets—one with more limited coverage from the Organisation for Economic Co-operation and Development and another constructed using general government gross fixed capital formation—to test for the relative effects of infrastructure versus non-infrastructure investment on output per worker, between developed and developing economies. The paper presents evidence that increasing infrastructure per worker has a larger relative impact on developing economies. This also implies that the share of gross capital formation devoted to infrastructure should be higher in developing economies.

Bank Lending—What Has Changed Post-Crisis?

By Jang Ping Thia

Using syndicated loan data, this paper finds that loan spreads have increased and have remained elevated post-2009. Regressions, controlling for currency fixed effects, loan types, loan sizes, number of participating banks and tenors confirm the higher spreads post-2009. Further analysis reveals that the average number of banks per syndication increased for developed economies but decreased for emerging economies. This is explained by the higher market shares of non-Japanese Asian banks in developing economies post-crisis, but with lower syndication intensity. Consistent with the capital shock hypothesis, Western and Japanese banks intensify the degree of syndication post-crisis, but other Asian banks do not. The lower syndication intensity suggests that market efficiency has declined for developing economies. Syndication should be further encouraged to reduce spreads.
